Iowa's seasonally adjusted unemployment rate increased slightly to 3.8 percent in March from 3.7 percent in February. The state's jobless rate was 3.7 percent one year ago. The U.S. unemployment rate increased to 5.0 percent in March. "Although a few sectors of Iowa's economy, such as construction, continue to expand, Iowa's unemployment rate ticked up in March, confirming signs of weakness in other sectors, particularly manufacturing," said Iowa Workforce Development Director Beth Townsend. "However, the good news is, as evidenced by the 54,000 jobs listed on our website, Iowa employers are still hiring." The number of unemployed Iowans rose to 65,300 in March from 63,200 in February. The current estimate is 2,400 higher than the year-ago level of 62,900. The total number of working Iowans decreased to 1,649,400 in March. This figure was 1,600 lower than February and 12,100 higher than one year ago.
